Owen said once the front moves through, a ridge of high pressure will lie over the country and bring settled weather on Tuesday and Wednesday.
Westland and Fiordland are expected to cop the worst weather in the form of heavy rain from the front moving up the country today, which is expected to cross the Southern Alps and into Southland.
“We will also be seeing rain in general right across the South Island,” said Owen, adding there will be some strong northwesterly winds through the Canterbury high country and inland parts of Canterbury.
NIWA reported this morning that the gusty southerly changes will cause a temperature drop of 5C to 10C in the South Island and Wellington will experience the impact of the southerly tomorrow.
